How the FCC actually handles “Fairness Doctrine”; complaints was the topic of Bradley Canon's 1967 Ph.D. dissertation, completed in the University of Wisconsin. Dr. Canon currently is assistant professor of political science at the University of Kentucky.  相似文献

In this article, Bradley Wade Bishop sets forth the unspoken premise that public libraries that offer desired services to their constituents are going to succeed. This article has many specific examples of emergency and continuing services that small public libraries provide. It also suggests the need for extensive research on successful libraries which illustrate all sorts of rules about how to meet the future successfully.  相似文献

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (= 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (= 2519), (B) 5th–8th ranking (= 2965), (C) 9th–14th ranking (= 4448) and (D) 15th–20th ranking (= 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (< 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (< 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (< 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (< 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (< 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (< 0.001; ES: 0.30–0.38), Tier C (< 0.001; ES: 0.46–0.54) and Tier D (< 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers.  相似文献

The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense “transitions” (= 45) and the start of offensive plays due to the rules of the game (= 45) were the most common type of sequences that resulted in goals compared to other patterns of play. The central offensive zonal areas were the most common for shots on goal, with 73% of all goals scored from these areas of the pitch compared to defensive and wide zones. The foot was the main part of the body involved in scoring (= 114). T-pattern analysis of offensive sequences revealed regular patterns of play, which are common in goal scoring opportunities in futsal and are typical movement patterns in this sport. The data demonstrate common offensive sequences and movement patterns related to goals in elite futsal and this could provide important information for the development of physical and technical training drills that replicate important game situations.  相似文献
